Fair Value Measurements
 
In accordance with ASC 820, the Company uses various inputs to measure the 2016 Warrants on a recurring basis to determine the fair value of the liability. ASC 820 also establishes a hierarchy categorizing inputs into three levels used to measure and disclose fair value. The hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to unobservable inputs. An explanation of each level in the hierarchy is described below:
 
Level 1 – Unadjusted quoted prices in active markets for identical instruments that are accessible by the Company on the measurement date
 
Level 2 – Quoted prices in markets that are not active or inputs which are either directly or indirectly observable
 
Level 3 – Unobservable inputs for the instrument requiring the development of assumptions by the Company
 
The following table summarizes the Company’s 2016 Warrants measured at fair value within the hierarchy on a recurring basis as of September 30, 2016:
